Patent number: 8377239Abstract: The operation of tow cutters in an automatic fiber placement machine are monitored to determine if inconsistencies in fiber placement are related to cutter operation. A machine vision system detects inconsistencies in tow placement, and timing signals are generated that represent the actuation of the cutters. The timing signals are correlated with recorded images of the placed tows to determine if the inconsistency in tow placement is related to cutter operation.Type: GrantFiled: July 7, 2010Date of Patent: February 19, 2013Assignee: The Boeing CompanyInventors: Roger W.

Patent number: 8184281Abstract: Methods for determining an inconsistency characteristic of a composite structure, such as inconsistency density-per-unit area. In one implementation, a method is disclosed for determining an inconsistency characteristic of a composite structure. The method involves determining a first distance from a first reference point of the composite structure to an inconsistency; determining a second distance from a second reference point of the composite structure to the inconsistency; using the first and second distances to establish a reference area of the composite structure; and considering each inconsistency detected within the reference area and producing therefrom an inconsistency characteristic representative of the composite structure.Type: GrantFiled: June 10, 2010Date of Patent: May 22, 2012Assignee: The Boeing CompanyInventors: Roger W.

Patent number: 7978328Abstract: A course material that is applied to a substrate during fabrication of a composite item is inspected by a system that includes a vision assembly. The vision assembly includes an area light, a line generator, a sensor, and an image processor. The area light illuminates an area of the course material. The line generator generates a line of illumination across the area. The sensor captures an image of the area. The image processor analyzes the image. The image processor is configured to identify debris on the course material in response to the area light being activated and the image processor is configured to identify placement aberrations in response to the line generator being activated.Type: GrantFiled: April 22, 2008Date of Patent: July 12, 2011Assignee: The Boeing CompanyInventors: Roger W.

Patent number: 7889907Abstract: A system for inspecting a composite material laid onto a substrate by a lamination machine. An imaging assembly attached to a rear portion of a delivery head of the machine obtains an image of at least a portion of the laid material beneath the imaging assembly. A processor inspects the image to detect a flaw. This system can provide an image of laid tape obtained close to a tape compaction point and can be implemented as a retrofit or as original equipment in lamination machines.Type: GrantFiled: January 12, 2005Date of Patent: February 15, 2011Assignee: The Boeing CompanyInventors: Roger W Engelbart, Reed Hannebaum, Brian S Hensley, Timothy T Pollock, Samuel D Orr
